Using the Bottom Lock and the A-Scope

Warning
Navman fuel kits are only suitable for petrol/
gasoline engines. Fuel consumption can
change drastically depending upon the
boat loading and the sea conditions. Always
carry adequate fuel for the journey, plus a
reserve.
It is recommended that the fuel tank capacity is
measured by draining the fuel tank, then
Þ
lling
it to capacity. After
Þ
lling, note the reading from
the fuel dispenser’s gauge.
Note:
Beware of air pockets, especially in
under
ß
